STATES JULIUS O. RICHARDSON, OF COLUMBUS, OHIO, ASSIGNOR OF ONE-HALF OF HIS RIGHT TO HENRY A. LANMAN, OF SAME PLACE.

ROLL FOR FORMING CARRIAGE-CLIPS.

SPECIFICATION forming part of Letters Patent No. 226,109, dated March 30, 1880.

Application filed November 13, 1879.

To all whom it may concern:

Be it known that I, J ULIUS G. RICHARDSON,

of Columbus, State of Ohio, have invented a new and useful Improvement in Rolls forForm- 5 ing Carriage-Clips, of which the following is a clear, full, and exact description, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 represents a perspective view of a pair of rolls with my improvement attached. Fig. 2 is a cross-vertical section through the line .90 of Fig. 3. Fig. 3 shows a front elevation of the rolls. Figs. 4 and 5 represent a finished clip:

My invention relates to machines for formin g carriage axle clips, and is an improvement on patent N 0. 133,906, issued to Wm. S. Ward December 10, 1872.

It consists in rolls provided with alternating projections and depressions, with continuous grooves and plate-surfaces, for forming continuously the clip as the metal rod is fed into the machine, as hereinafter explained and claimed.

To enable others skilled in the art to make and use my invention, I will proceed to describe the exact manner in which I have carried it out.

In the drawings, A and B represent the pair of rolls, properly secured in the framework (l, and provided with the usual gearing.

0n the roll A are formed the alternate projections a and spaces a, so as to produce alternate projections and depressions on the roll, as shown in Fig. 2. The projections a are provided with the grooves 12, for forming the round or bolt ends of the clip, and the projections are of smaller surface than the spaces a, for forming the flat portion or body of the clip.

On the roll B are also formed similar projections (l and depressions cl. The projections and depressions alternate in position in grooves 12 on the projections 00 of roll A, as shown in Fig. 3. These grooves c extend into the channels 0 sufficiently far to form the shoulders f on the clip as shown in Figs. 4 and 5.

The operation of my machine is as follows: The rod of metal being passed in between the rolls, we will suppose first between the projection or enlargement to on the upper roll and the spaces d on the lower roll. Passing between the rolls, the round portion of the clip is formed in the grooves b and 6. Then the bar passes between the projection 01 of the lower roll and the depression a of the upper roll, Where the flat portion or body of the clip is formed with its facein the same, or nearly the same, plane with one side of round or end portions of the clip, as shown in Fig. 5.

The operation of my rolls is continuous, and the ends of the clips are all formed round, with full shoulders and of uniform size, ready for screw-threading.

I am aware that the rolls of W. S. Ward form the ends of the clip round and ready for screw-threading; but by those rolls, which are 7 5 not continuous in action, only a single clip can be formed at one operation of the rolls.

I am also aware that it is not new to form clips continuously by passing the metal between rolls but heretofore this has not been a success, as the ends of the clip had one flat surface, and, being passed through the rolls, had again to be manipulated and rounded by hand, which rendered the clips too expensive for practical use.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a machine for forming carriage-clips, the roll A, provided with the projections to, havo ing the grooves b and the spaces a, in combination with the roll B, provided with the projections d, havingthe channel 0, and the spaces (1, having the grooves c, all constructed to operate substantially as and for the purpose de- 5 scribed.
